  • Citrix: Resolve SSL Error 61 on Windows

    Some weeks ago, I had a user call in, saying that she got the following error message when trying to launch applications from our Citrix farm: Luckily, this error is readily remedied, by installing an update for Root Certificates from Microsoft. Once the update was installed, the application launched without further incident.

  • Unable to uninstall Citrix Receiver or Online Plugin

    From time to time, users call in, reporting problems opening applications or desktops in Citrix. One of the many items in a support technician’s bag of tricks, is the old uninstall and reinstall routine. There are many reasons why this can be a good idea, among them that removing legacy applications that have been superseded by new versions…

  • Disconnect non-mapped drive

    From time to time, I have been unable to connect to the UNC path of a network share. The error message I get is: This usually happens when I am remotely connected to another user’s computer. The message is straight-forward enough; so, too, is the solution. You simply need to disconnect from the share. Here’s how: Open a command…

  • Unable to make Active Directory group member of another group

    Some time ago, I was working on a request to limit access to a folder to members of four AD groups. Following the established practice at my employer, I created the group to grant access to the folder, and the one to control who has access. I made the latter a member of the former, and…

  • RStudio does not detect R

    I recently had a user contact me to have R and RStudio installed. I downloaded and installed them both, and thought that would be the end of it. As it turned out, it wasn’t.

  • Google Accounts: Responding to calendar invites on behalf of other email addresses

    Here’s the scenario: You have set up your main email address to forward to your GMail address. Whenever you get calendar invites, you are unable to accept them, because they have been sent to your main email address, and not your GMail address. If that sounds familiar, I have good news: this can be fixed,…

  • Run Control Panel applets with elevated permissions

    Sometimes, you want to launch a Control Panel applet with elevated permissions. Normally, you would right-click the program you want, and select to run as an administrator. However, the control panel applets don’t give you that option, and so we need to go deeper. As it turns out, the Control Panel applets are all located at C:\Windows\System32,…

  • Force uninstall when installer is unavailable

    Imagine the scene; you are having a problem with a program, and the manufacturer tells you that the solution is a complete uninstall followed by a reinstall. You go to uninstall, and Windows tells you that it can’t find the installer. Looking around, nor can you. So, now you’re up a certain waterway without a certain…

  • List user home folder size

    Users tend to store all kinds of crud on their network home folders, which can be a constant source of frustration for SysAdmins. Luckily, it is fairly easy to get a list of the size of each folder, using a Powershell script. The script has already been made for us. It is discussed in detail here, and can…

  • Script output to file: Append -v- Replace

    By default, when running a script, the output is shown to you in the command line interface. Most of the time, that is exactly what you want. Some times, though, you are more interested in logging than in real-time data. The solution is to have the output sent to a file. As an example, imagine the…

  • Link without improving the link target’s search engine ranking

    You’ve done your research, and you are ready to publish an article which leaves the object of the article little or no honor. In order to prove your point, you need to link to a website run by the object of your article. You stop, and feel uneasy, as doing so will improve their search engine ranking.…
